Study On The Algorithm In The Analysis Of Robbery Crime Factors Based On Modified AHP-apriori

With continuous developing of the ministry of the public security information construction,and practice many years,security information center has accumulated lots of criminal data.However,currently,on the use of criminal data the public security department just simple inquiries,statistics and other traditional functions.Compared with traditional data analysis technology,the data mining technology can extract the hidden rules and trend from the existing criminal data,therefore,the public security systems urgent problem needs to study is how to use the data mining technology to realize the analysis of various factors of crime currently.“Two Robbery” crime is a greater influence on the social security multiple case,and endanger the citizen’s lives and property safety at any time,so reduce the frequent cases is a important task of public security organs.The generation of the case is dominated by various factors and it is also the result of interaction of each criminal factors.It can be reduce the crime rate if can find the contained rule in the criminal data to prevent and control of the preventive measures in advance.This essay attempts to combine AHP and Apriori association rules algorithms into the analysis of criminal causes,trying to get some causes of the crime,to provide the valuable information for the prevention and education crime,so it has the value of research and practical significance in the public security prevention and control.First this paper put forward four factor of “Two Robbery”: personal factors,social factors,time factors and spatial factors,and analyzes the influence of four factors on crime.Then the idea and realization process of AHP and Apriori association rules algorithm are expounded in detail.Finally,according to the lack of multi-level correlation analysis of Apriori algorithm,combine with AHP analytic hierarchy process for multi-level analysis to get the importance degree of influencing factors and influence factors of criminal associated.And from the results of “Robbery” crime factors affecting some of the rules and characteristics,and provide a new direction for public security prevention and control.
